“We see the history of the world as a series of crises in a conflict between two opposing philosophies. Ours is based on the notion that life, consciousness, intelligence, ego is the important thing in the world.”...“That puts us in conflict with every force that tends to destroy, deaden, degrade the human spirit, or to make it act contrary to its nature.”

— Robert A. Heinlein Off the Main Sequence (2005)
